ROTARY PUMP.

Specification of Letters latent.

Patented May 12, 1914.

To all whom it may concern:

Be it known that I, SAMUEL W. Esote- TON, acitizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Rotar Pumps, of which the following is a speci cation.

This invention relates to rotary pumps and an object to be attained is the produc tion of a pump that will be efficient in operation, economical in construction, and durable in service.

With this and other objects in view the invention consists of the novel construction and arrangement of parts set forth, and illustrated in the accompanyin drawlngs which form a part of this specification, in'

which is set forth an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to that come within the scope of the claimsappended hereunto.

In the drawings, in which like reference characters indicate like parts in the different views; Figure 1, is a side elevation of an embodiment of the invention; Fig. 2, is a central vertical section; Fig. 3, an elevation of the inside of the casing, on a reduced scale; Fig. 4, an elevationof the inside of the cover, on a reducedscale; Fig. 5, a view of the face of the rotor; Fig. 6, a view of the back of the rotor; Fig. 7, a plan view of-the pump; Fig. 8, a side elevation of the valve; Fig. 9, a perspective of the bushing.

7 Referring to the drawings -1-- indicates a circular, cup-shaped, casing having an outer chamber --2 and an inner chamber --3- of less diameter and having a flange -4- around the open end thereof affording means whereon a cover 5- ma be secured by suitable means such as olts 6--. A hearing --7--, in the closed end of the casing, provides for the passage of a shaft --20, a stufling box 8 bein provided on the exterior of the bearing. ithin the chamber 3 is disposed a concentric ring -9- spaced from the wall of the chamber and of suitable height to provide a bearing therebetween for rings on a rotor to be hereinafter described. Midway between the ring 9 and the wall of the easing are induction and 'eduction ports --10-- and -1lspaced 0. suitable distance apart. Annrc-shaped discharge block -12- 0ccuples the space between these ports. The lnner face-13* of the chamber 3 and the outer side -14- of the ring 9 are tapered toward the bottom of the casing, as are the sldes of the discharge block 12. A rotor, or irnpeller, --15 is rovided that fits within the chamber 3. n the face of the rotor are concentric rin s --l6 and 1 7- spaced apart to provi e. a raceway -18-. Thesides of the rings 16 and 17 are tapered to allow them to seat between the side 14 of the ring 9 and the wall of the chamber, and to permit the discharge block to seat within the raceway. The rotor is further provided with a hub that is bored out for the reception of a shaft -20- the rotor being secured thereon by suitable means such as a key 21--. A plurality of valves, or intercepters, --22- are disposed centrally in the course of the raceway, and are adapted to be oscillated in a plane parallel with the axis of the rotor. The body -23- of the valve is larger in diameter than the width of the raceway, encroaching respectively upon the rings 16 and 17, and has a tapered base --24.--, a stem --25-, the endof the stem being adapted, as by having a squared portion -26-, to receive a dog 35--.. Ex-

tending from the face of the valve is a sector shaped portion -27--,thut, in the open position of the valve, lies within the confines of the outer ring 16 (as shown at 27 in Fig. 5.) and at other times lies across the raceway '(as shown at 27" in Fig. 5).

In the side of the ring17, in proximity to each valve is a recess --28 in which is located a stop block .-29 that extends.

across the face of the valve into position to serve as an abutment for the sector 27. The

valve parts subject to wear require occa:

45 48 and --50 located respectively in raceway in the rotor:, and the other end has a projection that serves to hold the- -36- and 36- and is secured on the squared portion 26 of the valve stem by suitable means such as a set screw 37-. Pins .-38 are so positioned on the back of the 'j rotor as'to limit the throw of the dogs, the

arrangement being such that the dog strikes the pin at the moment the sector 27 assumes the desired position.

On the inner side ofz-the cover 5 an arcshape'd' block --39--'is secured in such relationshi to the discharge block. 12, on the casing, t at as the rotor turns, in the direction of the arrow, an arm.-'-36- on the dog attached toone of the valves, will contact with the end 40 thereof, turning the-valve until the sector. 27 retires within the limits of the .ring 16 into position to pass over the discharge block '12, the arm 36 contacting with a pin 38 and the side of the arm sliding over the block 39; as the end of the arm 36 escapes from the block 39'thearm 36 is in position to strikean angular'extension -41--, on a semi-circular member'42, shifting the valve in the opposite direction, bringing the arm 36 30.

against a pin 38, and placing thevsector' 27 across the raceway the side of the dog will lie in contact with the circle 42 holding the valve steady durin the continued movement of therotor. T e valve openin and closing blocks 39 and 42 are removab y attached to the cover in order that they may readily be replaced in case of wear. A bearin 43 in the cover is adapted to receive a ball-bearing thrust member -44-*.

A plate -45 covering the outer end of the I bearing is provided with a screw- "threaded aperture through which a screw .46' extends that is adapted to adjust the osition of the thrust bearing 44. Handoles -47'- and --49 having closures the cover and casing, and being positioned I. opposite each other, provide access to the valves" and bushings. By removing the closure 48a .tool may be introduced through the manhole 47, the set screw 37 loosened,

I the dog 35 removed from the valve stem, the dowel screw 33 taken out, then by exerting pressure from the other side, through Starting from the position shown in the drawings therotor turning in the .direc- 'tion of t e arrow, as the sector 27 clears the-block 12, the arm 36 of the dog clears the block 39, thearm 36' contacts-with extension 41 turning the valve and placing the sector 27 across the raceway 18, this impounds the fluid between the sector just slnftedand the preceding one, the movement of the valve creates a partial vacuum induction port. As a valve approaches the eduction port an arm 36 on a dog comes into contact with the end of the opening block 39 and the sector is shifted from the 7 position across the raceway into position to pass over the discharge block and the fluid that was impounded between 1t and the succeeding valvewill be forced out through the eduction port. This sequence of movements' recurs constantly. It will be observed parts one of which is constantly drawing fluid through the induction port, another carrying the impounded fluid around the circleand the third is forcing fluid out through the eduction port, this results in a constant flow of fluid.

It is obvious that 1 the pump may be mounted in any desired position, vertical or horizontal, and driven by any suitable means, direct coupled to an electric motor,

a turbine engine or otherwise. I have illustrated it as mounted on a base -'-51 and associated with the back of the casing for shifting said intercepters. V
